SGM9203 Triple, 6th-Order, Video Filter Driver for SD/PS/HD (1080i)/HD (1080p)

Transcription

1 SGM923 for SD/PS/HD (18i)/HD (18p) PRODUCT DESCRIPTION The SGM923 is a comprehensive filtering solution designed to give designers the flexibility to easily filter and drive various video signals, including high definition video, DVD and set-top box applications. The SGM923 offers 6th-order output reconstruction filter on all three channels. Filter channels are specialized for either component (YPbPr) or RGB video signals. These channels offer selectable frequency response of 8MHz, 18MHz, 38MHz or 75MHz. Additional functionality of these channels includes input biasing mode and output disable. The SGM923 may be driven directly by a DC-coupled DAC output or an AC-coupled signal. All inputs accept standard 1V PP video signals. Each channel includes an output amplifier capable of driving a single (15Ω), AC- or DC-coupled video load. All outputs can be disabled. The device is available in two factory-set options, a 6dB gain option and a db gain option. SGM923 is available in Green TSSOP-14 package. It operates over an ambient temperature range of -4 to +85. FEATURES Triple 6th-Order Video Reconstruction Filters Operates from 3.3V to 5.5V Single Power Supply Output Disable Supports Component YPbPr or RGB Video Three Channels, Selectable to 8MHz, 18MHz, 38MHz, 75MHz for SD/PS/HD (18i)/HD (18p) Applications 6dB Gain Option Available for 15Ω Double Terminated Video Load db Gain Option Available for High Impedance Loading Selectable Clamp or Bias Mode on Pb/B, Pr/R Inputs Available in Green TSSOP-14 Package -4 C to +85 C Operating Temperature Range APPLICATIONS Cable and Satellite Set-Top Boxes Projectors Communication Devices Portable and Handheld Products Personal Video Recorders Video on Demand DVD Players HDTVs REV.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. CAUTION This integrated circuit can be damaged by ESD if you don t pay attention to ESD protection. SGMICRO recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. SGMICRO reserves the right to make any change in circuit design, specification or other related things if necessary without notice at any time.
